The Sumoto ONK T 100 4" Submersible Peripheral Bore Pump is a high-pressure bore pump designed for domestic water supply, pressure boosting, and elevated tank filling where reliable head performance is required from a compact submersible pump. Using a peripheral impeller hydraulic design, the pump produces strong pressure while maintaining stable flow, making it ideal for narrow boreholes and clean water applications.
The ONK series features a durable construction combining a 304 stainless steel motor casing and shaft with a nickel-plated cast iron pump head and stamped brass impeller for excellent corrosion resistance and long service life. High-quality radial and thrust bearings, IP68 motor protection, and Class F insulated copper windings ensure dependable continuous operation in submerged conditions.
The ONK T 100 is the three-phase version of the mid-range ONK model, delivering up to 63 metres of head while maintaining efficient flow, making it suitable for domestic bore installations, pressure systems, and elevated tank supply systems.
